eCardioVascular Beat

Antiplatelet medications, such as clopidogrel (Plavix) or prasugrel (Effient), are approved treatments that block the function of platelets in the blood, and prevent the formation of clots that could block blood flow to the heart. These medications are often used in patients who have had heart disease and who have undergone a procedure called angioplasty or stenting to open up a blocked artery feeding the heart.

The purpose of this study is to evaluate the effectiveness of these medicines and to examine how doctors prescribe these medications for short- and long-term use. This is an observational study, which means no investigational treatments or procedures will be performed as a result of this study. Subjects’ treatment and medical care will not change by taking part in this study. Physicians will continue to make all decisions regarding proper treatment and care.

Up to 17,350 people will take part in this study at 350 medical centers located around the United States. Up to 200 people may take part in this study at Providence St. Vincent Medical Center.

This is a prospective, multi-center, non-randomized study of the SilverHawk device in the treatment of atherosclerotic femoropopliteal and tibial-peroneal arteries. The objective of this study is to evaluate the intermediate and long-term effectiveness of stand-alone SIlverHawk device for endovascular treatment of peripheral arterial disease in these arteries.

The SilverHawk device is cleared for commercial use by the FDA. Follow-up assessments occur at pre-discharge, 30 days, three months (subjects who are classified at baseline as Rutherford 5 or 6 only), six months, and one year post-study procedure.
